Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Hereinafter, embodiments will be described in detail with reference to the accompanying drawings. The embodiments described below do not limit the scope of the invention described in the claims. Further, the entire contents of the configurations shown in the following embodiments are not limited to those necessary as a solution of the invention described in the claims.

Referring to fig. 1-2, the landfill cover membrane partition sealing system provided in this embodiment includes a landfill area, the landfill area is provided with at least one garbage partition trench 1 to divide two sides of the garbage partition trench 1 into two independent garbage stacks 2, the garbage partition trench 1 is provided with a cover membrane 3 inserted along a height direction thereof, and the cover membrane 3 covers top surfaces of the two garbage stacks 2, respectively, so as to separate the two garbage stacks 2. It should be noted that the "height direction" of the garbage partition trench refers to the arrangement state of the landfill covering membrane partition sealing system shown in fig. 1, and the vertical direction in the figure refers to the height direction. So set up, a neotype mode that covers the membrane subregion is inclosed is provided, can carry out the subregion to the heap fast inclosed, the landfill gas collection mode of gas collection under the cooperation membrane collects the landfill gas, with the landfill gas separately between each subregion, can control each gas collection region fast, local damage can not influence whole landfill gas concentration, effectively improve landfill gas collection efficiency, and cover the membrane subregion inclosed, every subregion covers the membrane area and diminishes, make and cover the membrane difficult by wind lift, improve and cover the airtight effect of membrane, reduce the potential safety hazard.

As shown in fig. 1, the garbage zoning trench 1 is a square trench, which facilitates construction excavation in an elevation landfill process. The height H of the garbage partition ditch 1 is 1.8-2.2 m, and the width W is 0.8-1.2 m. Through many times of actual construction verification, the observation effect reachs, and rubbish subregion ditch 1 highly H is preferably 2 meters, and width W is preferably 1 meter, and the subregion slot that forms this moment is convenient for not only construct, and it is better to keep apart the effect moreover, and when the cover film appears the damage, can effectively play the effect of cutting off, guarantees that the air does not get into other regions and reduces the landfill gas concentration in other regions.

In this embodiment, the bottom surface and the side surface of the garbage partition trench 1 are covered with the cover film 3, that is, the cover film 3 is tiled along the bottom surface of the trench and extends upwards along the side surface, so as to further enhance the isolation blocking effect and improve the partition sealing control of the garbage stack.

Specifically, cover membrane 3 is two and overlap the setting, and two first ends that cover membrane 3 are located the bottom surface of rubbish subregion ditch 1, and two-layer membrane tiling covers the bottom surface. The second ends of the two cover films 3 extend out of the garbage partition grooves 1 and stretch and tile towards the garbage stacks 2 on the two sides respectively so as to cover the top surfaces of the two garbage stacks 2. Therefore, the isolation area is divided by two layers, and the partition sealing effect is better.

In the embodiment of the utility model, two first end fixed connection that cover membrane 3 are in the same place, guarantee that two-layer membrane can not the dislocation separation each other, guarantee all the time to be double-deck isolation in the subregion ditch, arrange the membrane junction in the bottom in addition, also ensure that the two can not easily torn by wind, the guarantee can not cause to cover the membrane damage because of the junction disconnection and influence landfill gas concentration of collecting.

In the preferred scheme of this embodiment, two first ends that cover membrane 3 pass through single track welding fixed connection, and welding speed is fast like this, welding seam one shot forming, and welding strength is high, and the welding seam is smooth for connect more firmly reliably, be convenient for implement.

As shown in fig. 2, the waste partition trench 1 further includes landfill waste 4 filled on the cover film 3 to compact the cover film 3. Like this will cover in the membrane disect insertion rubbish heap body and compressed tightly, can play the effect of fixed cover membrane, compare in fixed with the cement piece, improved the fixed effect of covering the membrane.

As an alternative embodiment, the cover film 3 is a high density polyethylene film having a thickness of 0.75 mm or 1 mm. The high-density polyethylene film has good corrosion resistance, electrical property, moisture resistance, leakage resistance and environmental stress cracking resistance, high tensile strength, ageing resistance, stable and reliable material and long service life, and is suitable for closed isolation of landfill sites.

In practical application, the embodiment provides a partition sealing manner for a landfill cover film, which is used for partitioning gas collection of a landfill body when landfill gas is collected in a landfill, and is used for partitioning and sealing when the landfill body is covered by the cover film. The method specifically comprises the following steps: after the landfill area is compacted and leveled, digging at least one garbage partition ditch 1 on the landfill area, preferably, the garbage partition ditch 1 is 2 meters high and 1 meter wide; placing the cover film 3 welded by the single rail into the bottom of the garbage partition groove 1, and tiling along the bottom surface and the side surface of the garbage partition groove 1; filling the garbage partition trench 1 with the landfill garbage 4 generated by trenching, and compacting and leveling; the cover film 3 is stretched and laid flat to the two garbage piles 2 on both sides to cover the top surfaces of the two garbage piles 2. The covering film sealing mode can quickly seal the garbage stack in different regions without mutual interference, effectively improves the landfill gas collection efficiency, ensures the landfill gas concentration of each region, and can fix the covering film so that the covering film is not lifted by wind.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention.
